三种填塞材料在鼻内镜下鼻腔泪囊吻合术中的应用

目的 探讨三种填塞材料在鼻内镜下鼻腔泪囊吻合术中的应用效果。 方法 将慢性泪囊炎患者90例（90眼）纳入前瞻性单盲研究，随机分为纳西棉组、膨胀海绵组、凡士林纱条组，每组30例（30眼）。所有患者均行鼻内镜下鼻腔泪囊吻合术。3组患者分别置入纳西棉、膨胀海绵、凡士林纱条进行填塞止血。比较3组疼痛视觉模拟评分法(Visual Analogue Scale，VAS) 评分、手术疗效和并发症发生情况。 结果 纳西棉组VAS评分低于膨胀海绵组和凡士林纱条组，手术总有效率高于膨胀海绵组和凡士林纱条组，差异有统计学意义（P＜0.05）。3组术后并发症发生率差异无统计学意义（P＞0.05）。 结论 鼻内镜下泪囊鼻腔吻合术中应用纳西棉填塞,可减轻患者术后不适，并加速鼻黏膜上皮再生,减少粘连和肉芽肿发生率，提高手术成功率。

Application of three packing materials in endoscopic dacryocystorhinostomy

Objective To investigate the application effect of three different packing materials in endoscopic dacryocystorhinostomy.Methods Ninety patients(90 eyes) with chronic dacryocystitis were included in the prospective single-blind study and were randomly divided into nasopore group, merocel group and vaseline gauze group, with 30 cases(30 eyes) in each group. All patients underwent endoscopic dacryocystorhinostomy. The patients in the three groups were filled with nasopore, merocel and vaseline gauze to stop bleeding separately. The visual analogue scale(VAS), surgical efficacy and complications were observed.Results The VAS of nasopore group was lower than that of merocel group and vaseline gauze group, and effective rate was higher than that of merocel group and vaseline gauze group, suggesting significant difference(P＜0.05). There was no significant difference in the incidence of postoperative complications among three groups(P＞0.05).Conclusion Nasopore used in endoscopic dacryocystorhinostomy can reduce postoperative discomfort, accelerate the regeneration of nasal mucosa epithelium, reduce the occurrence of granuloma and adhesion, and improve the success rate of operation.
